Cessna tail-cone reinforcement angle splice, installation kit, and method for installation thereof
A tail-cone reinforcement angle of a Cessna 180-185 series aircraft is repaired by the removal of an aft most section of that tail-cone reinforcement angle and its replacement with an elongated splice body. The elongated splice body is attached to the remainder of the tail-cone reinforcement angle and to the tail-cone portion of the fuselage of the aircraft. The aft section of the original tail-cone reinforcement angle is subject to the development and propagation of cracks in the area of the rear pivot shaft receiving bore, which cracks render the aircraft unfit for use. The invention includes the provision of a suitable elongated splice body, a method for its installation, and a tool kit which is usable in accomplishing the removal and replacement of the aft section of the tail-cone reinforcement angle.
1. A method for repairing a stabilizer pivot shaft receiving bore in a tail-cone reinforcement angle of a Cessna 180-185 series aircraft including:
disassembling a tail-cone section of the aircraft;
disconnecting a stabilizer rear pivot shaft bore section of the tail-cone reinforcement angle from the tail-cone section of the aircraft;
separating the stabilizer rear shaft bore section of the tail-cone reinforcement angle from an aft portion of a remainder of the tail-cone reinforcement angle;
providing a tail-cone reinforcement angle splice;
attaching the tail-cone reinforcement angle splice to the aft portion of the remainder of the tail-cone reinforcement angle;
securing the tail-cone reinforcement angle splice to the tail-cone of the aircraft; and
reassembling the tail-cone section of the aircraft.
2. The method of claim 1 further including providing the tail-cone reinforcement angle splice having an elongated splice body including a plurality of sections.
3. The method of claim 1 further including providing a plurality of rivet and bolt receiving bores in the elongated splice body.
4. The method of claim 1 further including forming a stabilizer rear pivot shaft receiving bore in an aft section of the plurality of elongated splice body sections after attaching the splice body to the remainder of the tail-cone reinforcement angle.
5. The method of claim 1 further including forming the elongated splice body of aluminum.
6. The method of claim 1 further including providing the elongated splice body having a generally rectangular shape.
7. The method of claim 1 further including providing a kit having the elongated splice body and further having tools and fixtures usable for attaching the elongated splice body to the remainder of the tail-cone reinforcement angle.
8. The method of claim 1 further including providing the elongated splice body having a forward overlap section having a first thickness.
9. The method of claim 8 further including providing the elongated splice body having a central, transition section, the central transition section having a section thickness greater than the first thickness of the elongated splice body.
10. The method of claim 9 further including providing an intermediate step between the forward, overlap section of the elongated splice body and the central, transition section of the elongated splice body.
